So, it worked?! Great. In the inlist we need to change classlib to classlibrary then..

With aMembers we can get events and properties. If we can get everything when we can write a script for creating a class, then instantiate an object of that class. So, it's possible, but as I said, it's more work involved, so I leave the exercise to the thread's originator.
If it's not broken, fix it until it is.
